Chapter Objective
This chapter describes installation of the 6181 Industrial Computer
including how to install the 6181 Computer in a panel using mounting
studs or clips.
European Union Compliance
The 6181 Computer meets the European Union Directive requirements
when installed within the European Union or EEA regions and has the CE
mark. A copy of the Declaration of Conformity is available at the
Rockwell Automation/Allen-Bradley Internet site: www.ab.com
ATTENTION: The 6181 Computer is intended to
operate in an industrial or control room environment,
which utilizes some form of power isolation from the
public low voltage mains. Some configurations may not
comply with the EN 61000-3-2 Harmonic Emissions
standard as specified by the EMC Directive of the
European Union. Obtain permission from the local power
authority before connecting any configuration that draws
more than 75 watts of AC power directly from the public
mains.

Publication 6181-IN002C-MU-P
Environmental Considerations
Mount the 6181 Computer in a panel or enclosure to protect the internal
circuitry. Versions with a gasketed bezel meet NEMA Type 1, 12, 13 and 4
(Indoor use) and IEC IP54, IP65 only when mounted in a panel or
enclosure having an equivalent rating. The non-display version does not
have a gasket and has a NEMA Type 1 and IEC IP2X rating.
Allow enough room within the enclosure for adequate ventilation. Also
consider heat produced by other devices in the enclosure. The ambient
temperature around the 6181 Computer must be maintained between 5°
and 50 °C (41°to 122 °F). The 6181 Computer is intended for use in
Pollution Degree 2 environments.
Make sure you provide provisions for accessing the back and side panels
of the 6181 Computer to install/remove components and to access the
floppy disk drive.
ATTENTION: The 6181 Industrial Computer is designed
for vertical panel-mount installation. Do not mount the
6181 Computer with DVD-ROM or CD-R/W option with
an angle more than 5 degrees from vertical. This may
cause operational problems with the DVD-ROM or CD-
R/W drive, and may result in damage to your media.

Mounting Clearances
Allow adequate space for mounting, air flow, and maintenance. The figure
below shows recommended minimum clearances to other components
within the rack or enclosure.
ATTENTION: The 6181 Computer should not be
operated within a confined space of the dimensions
shown below unless adequate ventilation or other cooling
methods are used to lower the air temperature within the
enclosure.

Panel Mounting with Mounting Studs
To install the 6181 Computer in a panel using 8 mounting studs:
ATTENTION: Disconnect all electrical power from the
panel before making cutout.
Make sure the area around the panel cutout is clear.
Take precautions so that metal cuttings do not enter any
components that are already installed in the panel.
Failure to follow these warnings may result in personal
injury or damage to the panel components.
1. Cut an opening in the panel using the appropriate panel cutout
dimensions provided on pages 11 or 12. Carefully drill eight 6.4 mm
(0.25 in.) holes for the mounting studs as indicated.
2. Make sure the sealing gasket is properly positioned on the terminal.
This gasket forms a compression type seal (NEMA Type 4). Do not
use sealing compounds.
3. Place the 6181 Computer in the panel cutout aligning the studs with
the mounting holes.
4. Install the 8 self-locking nuts hand tight.

Publication 6181-IN002C-MU-P
5. Alternately tighten the self-locking nuts (use 3/8 inch socket) until the
6181 Computer is held firmly against the panel (see recommended
tightening sequence below). The amount of torque required increases
significantly as the gasket reaches the proper compression. Tighten
nuts to a torque of 2.7 N-m (24 in-lbs).
ATTENTION: Tighten mounting nuts to a torque of
2.7 N-m (24 in-lbs) to provide a proper seal and prevent
damage to the 6181 Computer. Rockwell Automation
assumes no responsibility for water or chemical damage
to the terminal or other equipment within the enclosure
because of improper installation.

Panel Mounting with Mounting Clips
To install the 6181 Computer in a panel using mounting clips:
ATTENTION: Disconnect all electrical power from the
panel before making cutout.
Make sure the area around the panel cutout is clear.
Take precautions so that metal cuttings do not enter any
components that are already installed in the panel.
Failure to follow these warnings may result in personal
injury or damage to the panel components.
1. Cut an opening in the panel using the appropriate panel cutout
dimensions provided on page 13.
2. Make sure the 6181 Computer sealing gasket is properly positioned on
the terminal. This gasket forms a compression type seal. Do not use
sealing compounds.
3. Place the 6181 Computer in the panel cutout.

5. Gradually tighten the clips one at a time around the bezel using the
specified sequence. Repeat this process at least three times until the
clips are hand-tight and the gasket is compressed uniformly against the
panel.
6. Tighten mounting clips to a torque of 10 in–lbs (1.1 N•m) in the
sequence shown above. Do not over–tighten.

ATTENTION: Tighten mounting clips to a torque of
10 in–lbs (1.1 N•m) to provide a proper seal and prevent
damage to the 6181 Computer. Rockwell Automation
assumes no responsibility for water or chemical damage
to the terminal or other equipment within the enclosure
because of improper installation.
Connecting Equipment in Hazardous Locations
Specific configurations of the are certified for Class I, Division 2, Groups
A, B, C, D, T4A temperature code, hazardous areas. When installing the
